"Thank you seniors for your advice, the kid knows it. Ishikawa arched his hand and left the Immortal Mansion.

The spiritual spring seed is undoubtedly a good thing, but the current Ishikawa is not blessed. And Lin Feng knew very little about this, what he said could only be used as a reference.

At this time, the night was already dark, and there were many deaths and injuries of the Soul Devouring Demon Bat, and some of them left the hole.

Ishikawa knew that time was pressing, and he didn't delay any longer, so he collected the formation and put away Xin Rugou's storage bag. Go deeper into the cave.

There are a lot of demon bats dead in the cave, and the demon pill can't be wasted.

Turning that corner again, Ishikawa suddenly felt an inexplicable spiritual power fluctuation in front of him.

Hold your breath and secretly look inside, a huge soul devouring demon bat is devouring other demon bats, the snow-white fangs directly pierced into the bodies of other demon bats, and in a moment, the bitten soul devouring demon bat shrank at a very fast speed, and finally fell to the ground.

What surprised Ishikawa even more was that the other Soul Devouring Demon Bat did not react to this, even if the Soul Devouring Demon Bat was bitten, they did not resist, and let the huge Soul Devouring Demon Bat suck spiritual power, as if waiting in line to be sucked.

In the deepest part of this cave, the number of Soul Devouring Demon Bats is not very large, there are about a few hundred, and all of them are second-order Soul Devouring Demon Bats.

The place where the spiritual spring had just appeared was no different from before.

On the ground, the dried corpses of thousands of Soul Devouring Demon Bat were piled up, but Ishikawa knew in his heart that among these dried corpses, there would definitely be no demon pill.

Only a few Soul Devouring Demon Bats that have been killed by their own kind will have Neidan spawned.

Ishikawa looked at the Soul Devouring Demon Bat in front of him in surprise, and after absorbing the spiritual power of dozens of other demon bats, its coat color began to turn white to blood red, and its body size also swelled a lot.

"Whew!" the Soul Eater bat let out a rapid breath.

If there were hundreds of second-order soul devouring demon bats hanging in the cave, Ishikawa didn't even think about it, he turned around and left directly, there was no need to take risks for these demon beasts. But now it was different, the red Soul Devouring Demon Bat was quickly devouring the other kind, and as long as Ishikawa waited for a while, the demon bat could devour the same kind of kind.

With only one Soul Eater Bat, it's much easier to deal with.

After a little consideration, Ishikawa rearranged the concealment formation, although it was a waste of some spirit stones, but it was also worth it.

After arranging the concealment formation, there were only a few dozen soul devouring demon bats left in the cave.

The red Soul Devouring Demon Bat devoured its own kind without mercy, which made Ishikawa look a little frightened.

Ishikawa imitated the formation set up by Cangcun that day to besiege the Spirit Devouring Demon Bat, and arranged one in the tunnel, maybe it would be of some use.

After doing this, there was only one Soul Devouring Demon Bat left in the cave, and after devouring a large number of its kind, this Soul Devouring Demon Bat was covered in blood red.

Hanging from the rock wall, his body trembled slightly.

There was a "hiss" chirp in the mouth.

The fluctuation of the weak spiritual power on this soul-devouring demon bat naturally couldn't hide it from Ishikawa. The spiritual power on its body began to change dramatically.

"This Soul Devouring Demon Bat is going to advance!" Ishikawa has taken a cursory look at the "Beast Mind Method" in the past few days, and he also has some impressions of this, Ishikawa deliberately took out this book, and carefully studied it, and finally confirmed that this Soul Devouring Demon Bat is going to advance from a second-order demon beast to a third-order demon beast.

In the "Beast Heart Method", there are not many records.

The level of demon beasts is almost unchanged for a lifetime, and very few demon beasts can advance. Only those special demon beasts, such as demon Jiao, can reach the seventh order or even the eighth order or higher on average, while their juveniles are only of the third order, and this kind of demon beast advancement is very common.

But for ordinary demon beasts, such as the Cangyue Bear, he was a first-order demon beast when he was born, and he was only a first-order demon beast until he died, unless this demon beast accidentally devoured some heavenly spirit and earth treasure, it was possible to advance.

Therefore, it is a very rare thing to be able to see a demon beast to advance.

The demon beast advancement is not much different from the monk's advancement, and in the process of its advancement, it is the weakest.

Thinking of this, an idea suddenly popped into Ishikawa's heart. Ishikawa let out a trace of divine consciousness and slowly entered the head of the Soul Eater Demon Bat.

If he can subdue this Spirit Devouring Demon Bat as his own spirit beast, Ishikawa will have more helpers equivalent to the middle stage of foundation building.

What Ishikawa is worried about now is that if he takes advantage of the weakness of the Spirit Devouring Demon Bat to accept it now, I am afraid that it will affect the advancement of the Spirit Devouring Demon Bat, and if the advancement fails, it will be a bit of a loss. But if he doesn't accept it now, after the Soul Devouring Demon Bat successfully advances, Ishikawa will have no chance.

However, what made Ishikawa happy was that this Soul Devouring Demon Bat actually relied entirely on the devoured spiritual power to advance on its own, and in the skull, the primordial god the size of a grain of rice could not play any role at all.

And now, the Soul Eater Demon Bat didn't even put up any resistance.

Ishikawa was a little curious, and used his divine sense to wrap the spirit devouring demon bat's primordial spirit. In a matter of moments, the Soul Devouring Demon Bat was actually subdued by Ishikawa.

"This ......" Ishikawa smiled helplessly, it was too simple, too easy, and Ishikawa himself couldn't believe it.

However, now, the Spirit Devouring Demon Bat has indeed become Ishikawa's spirit beast.

On the body of the Soul Devouring Demon Bat God, the enchanting red light bubbled up, and it was obvious that the advancement had reached a critical period.

Ishikawa couldn't help much, so he simply went into the depths of the cave and searched the ground for the corpses of those Soul Devouring Demon Bats that had been killed by the attack of the same kind, these demon bats were at least first-order, and there were many second-order.

After a while, Ishikawa had already found dozens of first-order demon pills, and there were also four or five second-order demon pills.

The corpses of the other Soul Devouring Demon Bat were all sucked into dry corpses by the silver light emitted by the Spirit Spring.

Thinking of this, Ishikawa's face changed slightly, just by devouring so many Spirit Devouring Demon Bats, he had absorbed a considerable amount of spiritual power, plus the spiritual power that the spiritual spring had nurtured for thousands of years, how much spiritual power did there have to be in this spiritual spring seed?

At this time, the red light on the Soul Devouring Demon Bat seemed to be a little dim, and the advancement seemed to have come to an end. The figure of the Soul Devouring Demon Bat slowly became blurred, and finally, it disappeared from Ishikawa's sight. If it weren't for the fact that the Soul Devouring Demon Bat had become Ishikawa's spirit beast, and there was a connection between the two in divine sense, Ishikawa really couldn't see the Soul Devouring Demon Bat.

Bring the Soul Devouring Demon Bat into the Immortal Mansion. Ishikawa tidied up a little and walked out of the cave without stopping.

Xin Ru Hook is dead, and his men are in chaos. There should be no effective blockade, and leaving is the best time to do so.

And now the monks on the east side of the ancient ruins should also know about this. Therefore, the monks on the east side should try to avoid cannibalism.
